ABSTRACT. -Reported here are the findings of the first field surveys for amphibians in the CardamomMountains of Southwest Cambodia, which were conducted in January -March 2000 and February -April2001, A total of34 species of anuran were found in these mountains, including new species of Megophrys,Philautus and Rana (Sylvirana) that are described here. A further 17 species that have not previously beenreported from Cambodia were also recorded during these surveys. These results double the size ofCambodia's known amphibian fauna. Species of particular taxonomic interest from the collections arediscussed in further detail, and a national checklist of Cambodia's known amphibian fauna is also provided.

Variation. -The nine males and the young female collectedare all very similar. There is some variation in the presenceof the dorsal hourglass pattern, which may be obscured bythe general coloration of the back. The holotype is lighterthan other specimens that are almost all of a dark browndorsal colour. The ventral coloration is very similar in patternand intensity in all specimens. A few show indistinct bandson the throat and chest, but never the clear-cut longitudinalshoulder stripes that can be observed in M. major.

Ecological notes. -The holotype was collected on PhnomAural at an altitude of 800 m a.m.s.l., calling from the topof a boulder 0.2 m from a cascade section of a mountainstream in hill evergreen forest. The collection data for theholotype are typical of this species on Phnom Aural: maleswere found to be common along mountain streams in hillevergreen forest from 500 to 1,140 m a.m.s.l. They wereseen and heard frequently calling from cascade sections ofthese streams. Typically found sitting upright on boulderswithin the splash zone of falling water, males were alwaysobserved within 1 m of the stream, and usually no furtherthan 0.3 m from fast-flowing water. Towards the end of thesurvey period, when the first "mango" rains had began tofall, male M. auralensis were heard to call during and afterrain throughout the day, and particularly at dusk. Suchcalling behaviour, i.e. from cascade sections of mountain

Variation. -Morphometric variation is presented in table 7.Dorsal colour in most specimens is greyish brown, but manyshow light grey or blackish flecking reminding lichens. Thethroat never shows distinct darker coloration than chest andbelly. Vocal sacs are indistinct externally; sometimes a darkerzone can be observed where the vocal sacs are located. Thehumeral gland, that shows thickened glandular tissue whendissected, is indistinct by superficial observation in all males.

Ecological notes. -The holotype was collected from PhnomAural in hill evergreen forest at an altitude of 710 m a.m.s.l.The specimen was found sitting on a rock. 0.4 m from astream. Rana Jaber was found to be common and widespreadthroughout the Cardamom Mountains occurring in a rangeof vegetation types: dry dipterocarp. lowland dry evergreenand hill evergreen forest types, moorland areas on the top ofthe central range, and flooded forest in the Veal Vengwetland. Rana Jaber was recorded in heavily disturbed areasas well as in near-pristine forests. Typically this specieswas found close to permanent watercourses, often slowermoving sections of mountain streams.

Etymology. -This species is dedicated to Malcolm A. Smithin recognition of his work on Southeast Asian amphibians.Faber in Latin means "smith" or "craftsman working hardmaterial".

Remarks. -Rana (Sylvirana)faber is compared here to twosimilar species, R. nigrovittata and R. mortenseni. AlthoughR. mortenseni was recently regarded as a junior subjectivesynonym of Rana nigrovittata by Matsui et al. (2001), wehave unpublished infonnation indicating that the two species
